大丈夫。実妹の攻略本だよ。
A young man takes advantage of his little sister's bratty attitude to transform her into a submissive sexual partner. Through manipulation and coercion, he systematically breaks down her resistance, subjecting her to public humiliation and forced impregnation.
As the sister becomes pregnant, the brother asserts complete ownership over her body and future. Their twisted relationship deepens through increasingly bizarre scenarios, including encounters with a mysterious version of his sister named Alice and a mermaid fantasy. Each chapter explores a different facet of their taboo dynamic, pushing the boundaries of their forbidden bond.
